Abstract

AN AUTOMATIC MEASURING RANGE SELECTOR OF A DIGITAL MULTIMETER COMPRISES AN ATTENUATOR FOR ATTENUATING A MEASURED VOLTAGE OF A SUBJECT, AN A/D CONVERTER FOR CONVERTING AN ANALOG OUTPUT SIGNAL OF SAID ATTENUATOR TO A DIGITAL SIGNAL, A COUNTER FOR COUNTING THE DIGITAL OUTPUT SIGNAL OF THE A/D CONVERTER, A PARALLEL A/D CONVERTER FOR PROVIDING PARALLEL DIGITAL OUTPUT SIGNALS AND INCLUDING RESISTORS PROVIDING REFERENCE VOLTAGES, COMPARATORS FOR COMPARING AN OUTPUT VOLTAGE OF THE ATTENUATOR WITH REFERENCE VOLTAGES, AND AN ECODER CONNECTED TO THE COMPARATORS AND A CONTROL LOGIC AND MEASURING SELECTOR FOR CONTROLLING THE OUTPUT VOLTAGE OF THE ATTENUATOR ACCORDING TO PARALLEL DIGITAL OUTPUT SIGNALS OF THE PARALLEL A/D CONVERTER. ACCORDING TO THE PRESENT INVENTION, IT IS POSSIBLE TO MEASURE A SUBJECT WITH A VERY SHORT TIME SINCE A DESIRED MEASURING VALUE IS CONVERTED ONCE FROM THE A/D CONVERTER AND PROVIDED DIRECTLY.(FIG 4)
